Using British Libraries
First off, make the most of these collections. Most of the major museums in London have research libraries, all with their own rich collections and access policies.

Arlis.net Periodicals Database: The periodicals database is linked to a related directory of the art, architecture and design resources available in some 250 libraries, archives and other collections throughout the UK and Ireland. The directory provides a range of useful information, including postal addresses, web site addresses, opening hours and other details about access. It also indicates the subject areas covered by each organisation.
